Too Much "Glare"

try using a difuser thin sheet of white plastic or paper in front of the light source. That might help. Also set the white balance on the camera. Just sayin.

Is "glare" really what you're complaining about, as I don't really see any on the first pic? The second pic has a bit of over-exposure, but that is not really "glare" and can be fixed by adjusting exposure settings. Are you concerned that the surface scratches (esp on the first coin) are showing up more than you'd like? The lower the angle of the lights vs the coin, the more surface issues are emphasized. If you want to show the coin more like it looks in-hand, bring your lights up as high (angle, not distance) as you can get them and the surface issues will be de-emphasized...Ray

Judging from where the highlights are on your photos, I'd estimate your lights are around 50-60 degrees from horizontal. They need to be around 75-80 degrees or so to really de-emphasize surface finish, improve color, etc. You may also want to attempt axial lighting as an alternative. Long as the coins you're shooting are raw it will work fine.

This is the unfortunate downside of digital photography. What you're seeing in your images is a true rendition of the coin. If you look through a low-power loupe at the coin, under the exact same circumstances the camera is getting, you're going to see that stuff too. Generally speaking, though, that's not how we look at coins with the bare eye.

So, you're actually getting too good at this.

The ugly secret of photography is that a high AU-MS63 coin is actually kind of hideous.
